From that site: "Preamp tubes are not high voltage like power or rectifier tubes and will not cause a fuse to blow." Not so; preamp tubes are connected to the high voltage supply as well. Reference: http://www.schematicheaven.com/fender.htm
In a Fender Super AB763, for example, the power amp tubes are supplied with 460V and the preamp tubes get 410V.
Preamp tubes are low current, not low voltage.

You should send mesa/boogie an email and see if they'll fix that.

All in all a good article, with some excellent tips and information. But obviously, it is written for an audience with very little background in electronics. And therein lies the problem with "dumbing things down" to try and communicate with non-technical folks. The line between general observation and fact can be blurred, often causing those with technical knowledge and expertise to discredit the entire effort.
While it is unlikely that a preamp tube will fail in a manner which causes it to draw excessive current, I've definitely seen in happen many times. Perhaps they should have used a phrase along the lines of "highly unlikely."
